How to calculate position size from risk

The formula is simple: size = risk amount ÷ distance to stop. Move the slider — the calculator updates the size, position value and profit at the take-profit.

Deposit ⁦$100 000⁩, entry ⁦$77 265⁩, stop ⁦$78 848.9⁩

1%

10 stops in a row — minus 9.6% of the deposit

The classic risk management rule: no more than 2% of the deposit per trade.

Risk drives position size
Calculate your position

Risk management in trading starts with position size

By eye, it is easy to take a bigger size than planned: the stop is further than it looked, or the position was sized from margin with leverage. The calculator sizes the position so the loss at the stop is exactly your chosen percent.

Size fitted to each stop

A closer stop means a bigger size, a wider one a smaller size. The loss at the stop stays the same.

Loss known in advance

You see what the stop will cost you before you enter the trade.

A calculation, not advice

The calculator works with your numbers and never tells you what to buy.

Stop-loss, take-profit and fee calculator

Everything that changes the outcome is visible before entry: where the stop goes, how to take profit and what the exchange charges.

Calculate a trade

Stop-loss by price, percent or ATR

Set the stop the way you are used to. The size is recalculated so the loss at the stop stays within your chosen risk.

  • ATR stop by timeframe and number of candles — beyond market noise (PRO)
  • Distance to the stop in percent is shown next to the price
  • Changing the stop type does not change the risk amount

Split take-profits: closing a position in parts

Split the take-profit into parts, for example 70% at 2R and 30% at 3R. In PRO the calculator shows the price, size and profit of each part.

  • The price of each take by risk/reward ratio
  • How many coins to sell at each level
  • A hint when less than 100% of the position is allocated

Exchange fees and funding before entry

The calculator deducts entry and exit fees and 24-hour funding — you see net profit, not gross.

  • Entry and exit fees at your exchange's rate
  • 24-hour funding rate for futures
  • The size shrinks by the fees — the risk does not grow
